Why should people not see this film?

Why should someone see it?

Because it is a lame 1970's British comedy fill with mash banger jokes and their version of slap stick.

The big irony is all of that is the core message of the movie simply trades what it defines as one sheeplessly mindless unknowable world view, for another one.

Are you sure you're using the word "irony" correctly? Also the so-called "core message of the movie" which is discussed in the videos I posted, and at other events with the Monty Python crew, is not to challenge the teachings of Jesus, but rather to challenge his followers, some of which in this movie have gone on to follow Brian instead of Jesus.

As for your comment regarding British humour and film-making, might I point out to you that the longest running successful movie franchise is British and that their comedy shows are shown in series of 6-8 episodes unlike American shows which flog the dead horse for a full 22 episodes per series. Granted that did work quite well for Seinfeld, but for others like the Big Bang Theory, Two and a Half Men, etc, they are just nowhere near as good as they could be or as good as the comparable British versions were (e.g. Red Dwarf and Men Behaving Badly).

And I hear the Broadchurch remake was so bad people asked "why didn't they just show the critically acclaimed British original instead".
